We look at the division of 68656887 by 535 
The aim is to understand the frequency of 535 in 68656887.

Step 1:
535 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 535

Moving on to step 2:
68 divided by 535 is 0 with a remainder of 68.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 68 and we're left with 68.
Include the next digit (6) from the dividend after 68, then repeat: 686 / 535

Let's proceed to step 3:
If we divide 686 by 535, we get 1 and a remainder of 151.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 535 away from 686, we end up with 151.
Bring next digit (5) of the dividend behind the 151 and repeat the process: 1515 / 535

Let's proceed to step 4:
If we divide 1515 by 535, we get 2 and a remainder of 445.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we subtract 1070 from 1515, we get 445.
Include the next digit (6) from the dividend after 445, then repeat: 4456 / 535

Step 5:
When dividing 4456 by 535, we get 8 with a remainder of 176.
The number 8 becomes the next digit in our result. 
Result so far: 128.0
If we subtract 4280 from 4456, we get 176.
Take the next digit (8) from the dividend and append it to 176, then repeat: 1768 / 535

On to step 6:
The number 535 fits into 1768 3 times, leaving a remainder of 163.
Write down 3 as next digit of the result. 
Result so far: 1283.0
Subtracting 1605 from 1768 leaves us with 163.
Take the next digit (8) from the dividend and append it to 163, then repeat: 1638 / 535

Advancing to step 7:
If we divide 1638 by 535, we get 3 and a remainder of 33.
Record the quotient 3 as the next digit in the result. 
Result so far: 12833.0
Subtract 1605 from 1638 to get 33.
Fetch the next digit (7) from the dividend, attach it to 33 and continue: 337 / 535

Step 8:
The number 535 fits into 337 0 times, leaving a remainder of 337.
Put 0 as the next digit of the answer. 
Result so far: 128330.0
The remainder is 337 after subtracting 0 from 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

On to step 9:
If we divide 3370 by 535, we get 6 and a remainder of 160.
The number 6 becomes the next digit in our result. 
Result so far: 128330.6
The remainder is 160 after subtracting 3210 from 3370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 10:
1600 divided by 535 is 2 with a remainder of 530.
Record the quotient 2 as the next digit in the result. 
Result so far: 128330.62
If we take 1070 away from 1600, we end up with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Advancing to step 11:
535 goes into 5300 9 times with a remainder of 485.
The number 9 becomes the next digit in our result. 
Result so far: 128330.629
Subtract 4815 from 5300 to get 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Let's proceed to step 12:
535 can be fit into 4850 9 times, resulting in a remainder of 35.
The number 9 becomes the next digit in our result. 
Result so far: 128330.6299
If we take 4815 away from 4850, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final result is 128330.6299 with a remainder of 0.00035.
